QTR and AZO


 

With the help of Chris Anderson’s Ilford Classic and Warm-tone quad files I’ve have had good success in linearizing D Neg files. Also, vintage Portriga Rapid linearized very easily. However, beginning with the Lodima starter curve the lighter curve values for vintage AZO grade 2 simply will not linearize proportionately.

Any suggestions ??

Thanks in advance.

Can you send a screenshot of what the mapped curve looks like, like you did before? And are you exposing in the sun? My guess is you need to up your yellow with the yellow slider but won’t know until I see the mapped out curve.

Chris, did you send Steve a LUMEN curve for AZO?
?
Because 1: that is WAY too much black ink for a normal F2 Azo print, and 2: you asked if he was exposing with the sun? (Also, why are you wasting priceless and irreplaceable Azo on lumen printing???)
?
And everyone: Please stop using the General QTR group for questions about my software or curves. Please email me directly at support@... with the actual files (measurement and quad files) you have problems with and not just screenshots.

It is hard enough to do tech support as is, and always made worse having to undo other people's misleading or misunderstood recommendations.

Yes, Richard, that is a curve for an outside exposure full sun lumen print for Azo.

I use the Azo for lumen printing because my Azo is fogged; it’s fixed as per normal so it’s no different than a print done in a regular darkroom except for the light source (I always fix my lumens so they are archival). The profile works awesome and one simple test print if too much ink would tell the user to back off the ink load if exposing under an enlarger. For a lumen, that is the ink load necessary (around 60-65K for all papers) on a P900 with full sun exposure.

I will gladly no longer share my experience with QCDN on this list nor offlist as I get frequent requests off this list as well, probably because people are timid about posting their questions/experiences here and now I agree. I can sympathize with you how difficult it must be for you to troubleshoot your software for users.
